Driverless cars are coming soon. Driverless cars are very useful for three reasons.
First they can help people who can’t drive get around. This can help a lot of people. Second they can help people who don’t have a car get to far away places get to those places. Third they can act like a taxi and drive people to work.
There is a law in some states though. All driverless cars must have someone in it in case of of malfunction. This makes them safer.
